When looking for the icon to screenshot for you, I found I had to do some more digging.
DVD player is now located in /System/Library/CoreServices/Applications/.
I believe the icon is new, but I can't say I've looked at the app or used the app in many many years.
Attached is a screenshot of the about screen from DVD player. The DVD disc is the icon for the actual app.

It's new, here's what it looks like now: https://support.apple.com/guide/dvd-player/welcome-cp0cb9b5571d/mac
I'm quite surprised, I felt certain they'd can it.
